Although the merger remnant is massive, it is hot and more extended than a WD of the same mass that evolves as a single-star or grows by slow mass accretion [1]}. In addition the merger remnant is rapidly rotating and sustains a strong magnetic field. Future studies should determine the helium mass that can drive LTP/VLTP on such complicated WD-core merger remnants. In this study I scaled the required helium mass for an LTP/VLTP as in equation (REF ), but one should keep in mind that the required mass might be much smaller.
